The system accommodates multiple rod material options, allowing choice in rod flexibility and strength to match the demands of a variety of spinal conditions.
What is pedicle screw?
Pedicle screws are used sometimes in a spinal fusion to add extra support and strength to the fusion while it heals. Pedicle screws are placed above and below the vertebrae that were fused. A rod is used to connect the screws which prevents movement and allows the bone graft to heal.
Should pedicle screws be removed?
After the bone graft grows, the screws and rods are no longer needed for stability and may be safely removed with a subsequent back surgery. However, most surgeons do not recommend removal unless the pedicle screws cause discomfort for the patient (5% to 10% of cases).
What products do Medtronic make?

What is a fenestrated screw?
DESCRIPTION. The CD HORIZON™ Fenestrated Screw Set consists of a variety of cannulated screws. This cement is used to augment screw fixation into the pedicle in patients with advanced stage tumors with compromised bone quality.
Why do pedicle screws loosen?
It has been shown that the resection of ligaments, facet joints, and laminectomy are associated with the increased range of movements in a spinal segment and as a consequence, an increase in the stress on screw-bone interface that may lead to pedicle screws loosening.
Why do pedicle screws break?
A number of factors have been reported to be related to screw loosening. Excessive strain between the screw and bone interface is considered to be the primary cause for screw loosening [12, 22], which could be deteriorated when fusion is failure or the anterior support is inadequate.
